 I'm using IPO 9.1.8. My phones never ring busy and the caller hears either ringing or the caller goes to Voice Mail. If I'm using my phone any a second (or third) caller dials my number, I get one ring and a visual notification that there is another caller trying to reach me, then I have a choice whether or not I should switch callers. Not sure if this will help you.
